“…However, a reverse dynamics occurred at point P3, which is located in an area of small depth near the lakeshore, where water inlet from the surface runoff from a predominantly urban area occurs more strongly, limiting the concentration of sediment/pesticide particles. In studies developed by Barakat et al (2013) and Kafilzadeh (2015), heptachlor epoxide was found more frequently when compared to our study. High levels of this metabolite, such as that observed in the studied lake, indicate an aged presence of heptachlor (Barakat et al, 2013).…”

“…they have a very low solubility in water and a high solubility in lipophilic environments (Spiro & Stigliani, 2009;Baird & Cann, 2011;Girard, 2013). Studies have shown that DDT is still found in high concentration in the biota at various locations around the world (Kafilzadeh, 2015).…”

“…Furthermore, the few already performed have only assessed large lakes, where agricultural activity is predominant in the surroundings. Accordingly, we can mention the studies of Zhao et al (2010), Zhao et al (2010), Kuranchie-Mensah et al (2012), Wu et al (2013), Yuan et al (2013), Li et al (2015), Bettinetti et al (2016), and Hijosa-Valsero et al (2016) in freshwater sediments, and those of Barakat et al (2012b), Barakat et al (2012a), Barakat et al (2013), Kafilzadeh (2015), and Pinto et al (2016) in saline water environments.…”

ABSTRACT:The knowledge of pesticide residual concentrations in the environment is important to understand the threats to the environment and human health, especially when natural resources are used for human consumption. In this context, this study aimed to assess the potential ecological risk and respective sources of sediment contamination by organochlorine and organophosphorus pesticides. The study site was an urban lake located in Cascavel city, western Paraná state, Brazil, where the history of land use and occupation in the urban environment is typically agricultural. Surface sediment samples were collected every three months from April 2010 to June 2013 at five different collection points, totaling 65 samples. Analyses showed that contamination by organochlorine pesticides is related to agricultural activities in the past, with a low ecological risk to benthic organisms. Conversely, organophosphorus pesticides presented a recent and continuous contamination from urban activities, with a risk coefficient, especially for disulfoton, indicating a significant potential adverse effect on organisms. However, in general, the obtained results did not indicate an immediate risk to public health.

Pesticides used to protect the crops from pest attack in the agricultural fields pose harmful effect to the non-target organisms such as human and many other aquatic and terrestrial organisms either directly or indirectly through food chain. The present study was conducted to monitor a total of seven pesticide residues under organochlorine, organophosphorus and carbamate pesticides in three different sources of pond water, paddy field water and tube-well water from Nagarpur Upazila and paddy field water in the company of Dhaleshwari and Gazikhali river water from Saturia Upazila, Bangladesh. A total of 40 water samples were analyzed using high-performance liquid chromatography equipped with ultraviolet detector. Among the organophosphorus pesticides, diazinon was detected in eight water samples at a concentration ranging from 4.11 to 257.91 μg/l whereas, malathion was detected only in one water sample at a concentration of 84.64 μg/l and chlorpyrifos pesticide was also detected only in one water sample and the concentration was 37.3 μg/l. Trace amount of carbaryl was identified but it was below the detection limit. None of the tested water samples was found to be contaminated with DDT or its metabolites (DDE and DDD). The water samples contaminated with the suspected pesticides were above the acceptable limit except for the fish pond samples of Sahabatpur and Dubaria union. To control the misuse of pesticides and to reduce the possible health risk, appropriate control systems of pests such as integrated pest management system should be implemented immediately by the authorities of the country.

“…Organochlorine pesticides (OCPs) are characterized by low polarity, low aqueous solubility and high lipid solubility (lipophilicity) and as a result they have potential for bioaccumulation in food chain, posing a great threat to human health and the environment globally (Enbaia et al, 2014). Many OCPs have been implicated in a wide range of adverse human and environmental effects including reproduction, birth defects, immune system dysfunction, endocrine disruption and cancer (Kafilzadeh et al, 2012;Aktar et al, 2009). The aquatic life such as the fish populations, represent an important source of food for people (Veljanoska-Sarafiloska et al, 2011) and a way of transfer for these dangerous compounds to superior organisms.…”

The replacement of conventional sample preparation techniques with newer techniques which are automated, faster and more eco-friendly, is nowadays desired in every analytical laboratory. One of the techniques with the attributes mentioned above is the Accelerated Solvent Extraction. In order to evaluate how successful this method is for the extraction of fat and organochlorine pesticides (OCPs) from dried fish meat samples, we have tested two series of diverse fish using Dionex™ 350 ASE provided by Thermo Scientific™ (Germany). For a more interesting approach, we added to our investigation 7 polychlorinated biphenyl (PCBs), 3 thricholorobenzenes, 2 tetrachlorobenzenes, 1 pentachlorobenzenes and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The study focused on comparing the recoveries of these analytes from different fish samples, after replacing the conventional reference method of the laboratory with ASE. The ASE parameters tested were previously used for the extraction of fat and polybrominated diphenyl ethers (PBDE) from fish samples: temperature: 120 ° C; static time: 5 min; number of cycles: 3; flushing volume: 25%; rinse with nitrogen: 90 s; solvent: cyclohexane/ethyl acetate (ratio 1:1).The ASE method provided similar and in some cases better results when compared to the standard reference method, more rapidly, eco-friendly and safer. Any high or low recoveries of the analytes taken into study are attributed to random or systematic errors during the Clean-up step of the extracts and the quantification with Gas Chromatography coupled with Tandem Mass-Spectrometry (GC MS/MS).
